Hi, I tied searching for this but can't find anything. I am looking at buying an 09 883l that supposedly has 1200 kit installed, the kit number is 30003-10. I'm pretty sure its installed, the cylinders are all black and have an HD shield logo stamped on each cylinder on one side but on the other side I see what looks like a part number, 15956-02. Does anyone have this kit and can verify these markings? I always thought the part numbers after the dash were the year...
